Abstract

The article focuses on the recent progress and regulatory approval of therapies using induced pluripotent stem (iPS) cells in Japan for treating heart failure and Parkinson’s disease. Developed primarily at Kyoto University, these therapies utilize iPS cells—stem cells reprogrammed from adult cells—to regenerate damaged tissues while minimizing ethical concerns and immune rejection. Japan’s health ministry has granted conditional marketing approval for these treatments under a system that allows sales for up to seven years while further efficacy studies continue, bypassing traditional lengthy phase 3 trials. Meanwhile, other countries pursue more conventional clinical trial pathways for iPS and embryonic stem (ES) cell therapies, which remain under investigation for various diseases including diabetes, Parkinson’s, and epilepsy.
